Space and Time-Efficient Quantum Multiplier in Post Quantum Cryptography Era
IEEE Access, 2023 This paper examines the asymptotic performance of multiplication and the cost of quantum implementation for the Naive schoolbook, Karatsuba, and Toom-Cook methods in the classical and quantum cases and provides insights into multiplication roles in the ...

Trusted Noise in Continuous-Variable Quantum Key Distribution: a Threat and a Defense [PDF]
, 2016 We address the role of the phase-insensitive trusted preparation and detection noise in the security of a continuous-variable quantum key distribution, considering the Gaussian protocols on the basis of coherent and squeezed states and studying them in ...

HybridPKE: A forward-secure non-interactive quantum-safe hybrid key exchange scheme
Engineering Science and Technology, an International Journal, 2022 The schemes submitted to NIST call for standardization of post-quantum cryptography have some common drawbacks in terms of decryption failure probability, scalability, and switching issues from pre-quantum to post- quantum cryptography. In this paper, we
